Last 2 days I bought for about some cheap coins and it went down for about 5% or something and I decided to sell. And now, I am at full regret that all of those coins are now up for about 20%. My lesson for that is to be patient since the market was down for some day and it will always go back up.
knowledge, and always looking for information about the market situation and coins you have is a necessity. in crypto, we all know. patience is the main capital in any investment and trade related.
